15.07.2019· Silicon carbide has a similar hardness to those hard carbides but is not clearly harder, and in general silicon carbide is not as good at cutting steel as aluminum oxide. CBN and diamond are significantly harder than any of the carbides so they are generally better at least in terms of grinding and polishing high wear resistance steels with hard carbides.

Lapping Compound - American Lap

Silicon Carbide: Silicon Carbide is only suited for the lapping of hardened metals due to its characteristics of extreme hardness and sharpness. But because of its brittleness and tendency to break down into very sharp pieces, thus produces scratches. Silicon Carbide''s use is restricted to the lapping of most gears and large valves.
